About

These ROM boards are for Nissans that use a 64k program with a 20×2 header. These boards require TWO 512k chips such as the C2 SST27SF512 chip that we sell or a 27C512. They require the same ROM image to be burned into both chips. They do NOT support switching between ROMs – single program only. These do NOT work with Nissans that have 32k programs such as red-top S13 SR20DET, S13 KA24DE, etc. These boards can be used with TWO Ostrich 2.0 emulators for realtime tuning.
